I am wondering before I try to hook up this bad boy if anyone notices a difference and if it adds higher quality sound to your system? I have the double up on the tower and 6 wet sounds in the boat along with a 10" WS sub. I question this because one amp SYN4 runs the 4 inboat speakers and the sub. While another SYN4 runs my tower speakers. My head unit runs the 2 bow speakers.

Will it benefit my system? I was looking for more bass control. Since my sub is on my inboat speakers I will have no bass when I shut them off or down while surfing etc. Any suggestion would be great.

How should I wire?

Kinda of disappointed with this system thus far.... By the way I have a 2012 MB F21 Tomcat...
